Application filed September 8, 1914. i Serial No. 860,665.

To all whom t maycoacera: :Be itknown thatv I, YViLLIAM H. HIDLE- BAUGH,a citizen of the United States, residing at Gould, in the county ofHarmon, State of Oklahoma, have 'invented certain new and usefulImprovements in AirHose Couplings for Railway-Carsgand do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in theV art to which itappertains to make and use the: same.

This invention relates to air hose couplings for railway cars.

The object of the invention resides in the provision of a device of thecharacter named which will serve to automatically unite the adjacentends of train pipe sections of an air brake system when the carscarrying such adjacent ends of the train pipe are themselves coupled.

A further object of the invention resides in the provision of a trainpipe coupling in which the adjacent ends of the train pipe are normallyclosed by a valve associated with each section of the pipe, and whichembodies means whereby said valves are automatically opened byengagement of the Vcoupling heads with each other.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which* Figure 1 is aplan view of the coupling just previous to the movement of the partsthereof into coupling relation; Fig. 2, a view similar to Fig. 1 partlyin section and with the parts in coupling relation; Fig. 3, a side viewof what is shown in Fig. 2; Fig. l, a section on the line 4-f of Fig. 2;Fig. 5, a perspective view of a fragment of one of the coupling heads,and Fig. 6, a per-' spective view of the valve mounted in the head forclosing the passage therein, said valve being shown removed.

Referring to the drawings the coupler is shown as comprising a pair ofcooperating heads A and B which are pivotally connected at their innerends Within tubular draw `bars A and BV respectively. These drawlongitudinal movement and is` normally held at the limit of saidmovement in one direction by springsl 11. Projecting from the outer endof each draw bar A and B are leaf springs 12 which engage the sides ofthe associated head and resist any'tendency of such head to swinglaterally on its pivotal Aconnectionwith its draw bar. By thisconstruction, the outer ends of the heads A'and B are heldin'firmcontact when the associated cars are rounding a curve. Each of the headsA and B comprises a body 10 the outer end of which terminates in majorand minor V-shaped fingers 11 and 12 respectively, a resultant V-shapedrecess 13 being thereby formed between the fingers 11 and 12.

Each of the heads A and B is provided with a longitudinal passage 18 inthe inner end of which is engaged a pipe 14: which is connected to theadjacent end of a train pipe 15. The outer end of the passage 13 opensthrough the side of the linger 11 adjacent the finger 12. The flow ofair through the passage 13 is controlled by a valve 16 mounted in theassociated head. The valve 16 of each head A has secured thereto anoperating handle 17 having a cam edge 18. A spring 19 has one endsecured to the handle 17 and its other end anchored to the associatedhead, said spring constantly tending to move the valve 16 to closedposition. Movement of the valve 16 under the influence of the spring 19is limited by a stop 2O secured to the associated head and preventingmovement of the valve beyond closed position. Rotatably mounted upon thefinger 11 of each head at the point of said finger is a roller 21 whichis adapted to engage the cam edge 18 of the handle 17 of the valvemounted on the other head during the coupling operation for the purposeof opening the valve 16 automatically.

Upon movement of the coupling heads from the position shown in Fig. 1 tothe position shown in Fig. 2 it will be obvious that the fingers 11 willenter the recesses 13. During this movement of the heads A and.ourvedoutwardly as at 25 and serves to assist the heads A and B t0movetogether into interlocking relation.` The passage 13 is `alsocontrolled by an emergency valve 26 having a handle 27 adapted to`engage over `the pivotal connection between each head and theassoeia-teddraivbar to lock said valve 26 in open position.V

It Will be noted thatthe couplers herein ,described can be provided`with a plurality` of air passagesand vall of saidpassages Con-4 I p y Yto operate the valves to open position.
